My children love these & a simple online search provides lots of extra games & fun ideas if needed. We haven't had any problems with the inner dice getting stuck but they can be quite loud. I like that they come in a tub for storage & am pleased to report that they can withstand being thrown about by a 6-year-old, who clearly has inherited my (non) throwing capabilities!

I had expected that the internal die would be capable of moving, so that the number alignment would change. That does not occur. I was disappointed. My grandson uses the dice like blocks but they are less than they could be, and for the price are expensive blocks.
